Description

Technical Field

[0001] This invention relates to the field of strawberry cultivation, specifically to a device for digging up strawberry seedlings grown in soil. Background Technology

[0002] Strawberry seedlings are primarily propagated through runner division. However, when digging seedlings from the orchard for potting, it's crucial to retain as much soil as possible and preserve a sufficiently intact root system. The root system should generally be around 10 centimeters long. When removing strawberry seedlings from the orchard, a certain amount of potting soil should be included to prevent root damage. The runners connecting the seedlings to the potting soil should also be severed. Because the dug-up strawberry seedlings need to be transported to the plantation using specialized trays with standard indentations, and because strawberry runners have a certain degree of hardness and toughness, the trays also require specific shapes and sizes of potting soil. Therefore, a high level of skill is required from the workers digging the seedlings. Improper handling can significantly impact subsequent traying, transportation, and seedling growth. Since the distribution of strawberry seedlings from runner branches is irregular, mechanized digging is difficult. Current technology primarily relies on workers using shovels, which is labor-intensive, difficult, and inefficient. Summary of the Invention

[0003] To address the aforementioned problems, this invention discloses a seedling digging device for strawberry soil cultivation. This device generates a downward driving force through a rotating shaft, which drives the shovel blades to insert into the soil. Adjacent shovel blades cooperate with each other to cut the runners while digging, enabling fast, precise, and high-quality seedling digging.

[0004] To achieve the above objectives, the technical solution provided by this invention is as follows: A strawberry seedling digging device includes a sleeve, a supporting cylinder slidably connected to the outside of the sleeve, a rotating shaft rotatably connected to the inside of the sleeve, the lower end of the rotating shaft extending into the inside of the supporting cylinder, a pressure plate intermittently connected to the lower end of the rotating shaft, and multiple shovel blades evenly hinged to the circumference of the pressure plate, each shovel blade being slidably connected to the inner side of the supporting cylinder.

[0005] Preferably, the shovel blade has an inverted triangular structure, and the support cylinder has an upper cylindrical shape and a lower conical shape.

[0006] Preferably, both the left and right sides of the shovel blade are provided with cutting blades that cooperate with adjacent shovel blades.

[0007] Preferably, after all the blades are moved to the bottom, a root protection hole is formed at the bottom.

[0008] Preferably, the lower end of the rotating shaft is provided with a top plate, which is an inclined flange, and the lowest point of the lower end of the top plate is in contact with the upper surface of the pressure plate.

[0009] Preferably, the pressure plate is circumferentially hinged with multiple transmission rods, and each transmission rod has a shovel blade hinged to its lower end.

[0010] Preferably, the pressure plate is provided with a central hole, and the center of the top plate extends downward through the central hole and is connected to a pull plate, the diameter of which is larger than the diameter of the central hole.

[0011] Preferably, an upper limit plate is provided at the lower end of the sleeve, the upper limit plate is located inside the support cylinder, a lower limit plate is provided on the outside of the sleeve, and a spring is provided between the upper end of the support cylinder and the lower limit plate.

[0012] Preferably, the lower end of the support cylinder is provided with a plurality of concave clearance grooves at intervals.

[0013] Preferably, the inner wall of the support cylinder is provided with multiple sliding grooves that cooperate with the shovel blade.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The device rotates the top plate via a rotating shaft. The top plate pushes the pressure plate, which rotates coaxially with the top plate, to move downwards. The pressure plate drives the shovel blades to intermittently insert into the soil, encircling and excavating the soil around the strawberry seedling. At the same time, the cutting blades of adjacent shovel blades work together to cut the runners. The volume of the cultivation soil around the strawberry plant dug out by this device is uniform, making it easy to fill the trays. It can achieve fast, accurate, and high-quality seedling digging.

[0017] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0018] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0019] like Figure 1-10 As shown, this invention discloses a strawberry seedling digging device for soil cultivation. The device includes a motor 1, a rotating shaft 3, a top plate 7, and a pull plate 13 connected sequentially from top to bottom. A sleeve 12 is fitted over the rotating shaft 3. A handle 2 is symmetrically arranged on each of the left and right sides of the upper end of the sleeve 12. A support cylinder 6 is slidably connected to the lower outer half of the sleeve 12. The support cylinder 6 has a cylindrical upper part and a conical lower part, with the conical surface being a convex arc surface. Four grooves are provided on the inner wall of the conical structure to provide a guiding path for the shovel blade 8. Figure 1 and Figure 2As shown, multiple concave clearance grooves are spaced apart at the lower end of the support cylinder 6 to allow runners between adjacent strawberry seedlings to pass. Inside the support cylinder 6 is a pressure plate 9, with four transmission rods 10 hinged to its outer surface. Each transmission rod 10 has a corresponding shovel blade 8 hinged to its lower end. The shovel blade has a convex arc cross-section and an inverted trapezoidal outer surface. Both sides of the shovel blade 8 have cutting edges that cooperate with adjacent blades. When the shovel blade 8 moves downwards along the groove of the support cylinder 6, adjacent blades form a scissor-like cutting edge, severing the runners of the strawberry plant.

[0020] The number of transmission rod 10 and shovel blade 8 can be changed to three or five pieces according to requirements.

[0021] To prevent the strawberry plant roots from being cut off by the lower end of the shovel blades 8 when they reach the bottom, the lower end of the shovel blades 8 is designed as an arc in the horizontal plane. In this way, when the shovel blades 8 move to the bottom, the bottom of all the shovel blades 8 form a root protection hole. The capillary roots at the bottom of the plant are pulled out of the soil when the whole device removes the potting soil from the ground. Since most of the roots at the bottom are capillary roots and are protected by the whole clump of potting soil, the lower end of the roots will not be damaged when pulled out, and they will not be cut off by the shovel blades 8.

[0022] like Figure 10 As shown, the top plate 7 is an inclined flange. The motor 1 drives the rotating shaft 3 to rotate. The lowest point of the bottom of the top plate 7 moves in a circle along the pressure plate 9, generating a series of intermittent downward thrusts on each point on the same circumference of the upper surface of the pressure plate 9. The pressure plate 9 transmits this series of thrusts to the shovel blades 8 through the transmission rod 10, which in turn pushes the four shovel blades 8 one by one down along the sliding groove on the inner side wall of the support cylinder 6. The handle 2 is pushed down, and the lower end of the sleeve 12 pushes the top plate 7, continuing to generate downward thrusts on the shovel blades 8. The shovel blades can be easily inserted into the soil to complete the digging of the strawberry seedlings.

[0023] A central hole is provided at the center of the pressure plate 9. A vertical shaft is connected to the center of the top plate 7. The vertical shaft passes downward through the central hole and is connected to a pull plate 11. The diameter of the pull plate is larger than the diameter of the central hole. An upper limit plate 13 is provided at the lower end of the sleeve 12. The upper limit plate 13 is located below the lower surface of the top plate of the support cylinder 6. A lower limit plate 4 is provided outside the sleeve 12. A spring 5 is provided between the upper end of the support cylinder 6 and the lower limit plate 4.

[0024] When digging seedlings, after the support cylinder 6 contacts the ground, push the handle 2 downwards. The handle drives the sleeve 12 to move downwards along the support cylinder 6. During the downward movement of the lower limit plate 4, the spring 5 is compressed, allowing the sleeve 12 and the rotating shaft 3 to move stably and balanced downwards along the support cylinder 6, preventing tilting. After the seedling digging is completed, pull the handle 2 upwards. Under the restoring force of the spring 5, the sleeve 12 and the rotating shaft 3 can rise stably and balanced along the support cylinder 6, preventing tilting during the rise. After the upper limit plate 13 abuts against the support cylinder 6, the sleeve 2 will no longer continue to rise along the support cylinder 6, preventing it from detaching from the support cylinder 6.

[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
